Objective To inquire into the value of Liechtenstein Hernioplasty in the therapy of oblique or direct hernia.Method Liechtenstein was used in the therapy of 163 cases of oblique hernia (154 cases) and direct hernia (9 cases) from Feb.1998 to Jun.2001 and the clinical data was retrospectively studied.Most of them are of onset hernia except 8 cases of recurrent hernia.In 148 cases,the diameter of hernia ring is less than 2.5 cm and 30.1% of patients are elder than 65.The emergent operation was adopted in 12 cases.Results Off-bed exercises can be admitted at early stage of postoperation with slight pain and no local tension.Total recovery was obtained in 5-10 days after operation.After 6-36 months' follow-up,no mortality and less recurrence was detected.Conclusions There are so many advantages to treat oblique or direct hernia with Liechtenstein, such as minimized trauma, accelerated recovery,low recurrence rate and low cost. The indication of this operation involved all kinds of hernia (onset or recurrence of oblique or direct hernia,emergent operation of incarcerated oblique hernia, etc).

Objective Background and objective The Cox maze Ⅲ procedure has been considered the gold standard for the surgical treatment of atrial fibrillation (AF) and the modified Cox maze use bipolar radiofrequency ablation instead of the cut-and-sew technique,while also reducing the connecting lines in left atrium.This study was to understand whether completely isolation the posterior left atrium by increasing left atrium ablation lines can enhance the survival after modified Cox maze procedure.Methods From Jan 2009 to Dec 2009,all the patients underwent the Cox maze procedure,following the same examination,were divided into two groups (case-control): box lesion group (n =60),which is means the right and lefi pulmonary vein lesions were connected inferiorly by adding ablation lines,thereby completely isolating the posterior left atrium and the non-box lesion group (n =60).Similar interventions were given during the perioperative periods.Comparing the risk factors before surgeries,then follow-up was 100％ complete,and the mean follow-up was 9 ± 8.4 months.Results Except the box lesion had long time of extracorporeal circulation,the characteristics of the 2 groups were similar because there were no differences in age,AF duration,left atrial diameter,left ventricular ejection fraction or homochronous operation between the groups and there was no operative death.No patient was lost to follow-up.In the mean follow-up duration,a patient was died of intracerebral hemorrhage at 2 months postoperationly in the box lesion group and a patient suffered from stroke at 12 months postoperationly in the non-box lesion.The overall freedom from AF recurrence was higher in the box lesion group at 1 (70％ vs 51.2％,P =0.039) and 3 (78.3％ vs 60％,P =0.030) months.While it was 80％ vs 71.7％ (P =0.286) at 6 months.Eight patients wrere readmitted because of the recurrence of AF,4 and 2 patients underwent catheter ablation in box and non-box group respectively,one patient in each group underwent electrical conversion.After treatment,all of the patients were recovered to sinus rhythm and continued to take cordarone.Conclusion Compared to the single connecting between right and left pulmonary vein,isolating the entire posterior left atrium by creating a box lesion showed higher freedom from AF in the earlier months (1-3months).However,half a year after the surgery,there were no significant differences between the two groups.

Although the surgical techniques has already improved in heart transplantation, heart preservation is still the biggest obstacle to the surgery.At present, heart preservation effective time is only 4-6 hour.How to extent the time of heart preservation is a major research direction.Comparison of available preservations for heart transplantation based on its mechanism and the prospect of its Clinical application.

Objective: To evaluate the mitral, aortic and tricuspid valve replacement for rheumatic heart disease. Methods: From June 1990 to June 2001, 941 patients underwent valve replacement. Among them, 24 patients underwent simultaneously mitral, aortic and tricuspid valve replacement. There were 17 females and 7 males, with mean age of 36 years (ranged from 18 to 59 years). Eight patients had previous closed mitral valvotomy. Eleven patients complicated with left atrium thrombus, 16 with hapotomeglia, and 8 with ascites. The X ray results showed that the C/T ratio was 0.66 to 0.91. The heart function (NYHA) was class III in 9, and class IV in 15. All patients had combined mitral, aortic valve lesions associated with severe tricuspid valve regurgitation. Results: One patient died postoperatively with an operative mortality of 4.2%. 23 patients followed up from 20 to 36 months (mean, 26.4 months). There was no thrombolism and anticoagulant related hemorrhage. The echocardiography demonstrated the diameter of left atrium right ventricle, and LVDd significantly decreased after operation. The heart function was also significantly improved. Conclusion: The combination of mitral, aortic and tricuspid valve replacement could achieve a satisfactory result with low mortality and better recovery of heart function.

OBJECTIVETo summarize the clinical characteristics, surgical management and postoperative complications in patients with congenital bicuspid aortic valve (CBAV) over 50 years of age.

METHODSFrom January 2009 to September 2011, 73 CBAV patients aged 51-76 years (mean 61.8∓0.73 years) were treated in our center. Except for 1 patient who underwent Bentall surgery and another having Wheat surgery, all the patients received aortic valve replacement (AVR), including 7 with double (mitral and aortic) valve replacement (DVR), 6 with mitral valvular plasty, 11 with tricuspid valvular plasty, 8 with coronary artery bypass graft implantation, 1 with aortic-left ventricular tunnel repair, 1 with atrial maze ablation, and 1 with left atrial thrombosis removal.

RESULTSTwo patients died after the surgery, with a perioperative mortality rate of 2.7%. The cardiopulmonary bypass time was 78-217 min (mean 131.9 ∓6.0 min) with an aortic blocking time of 56-158 min (mean 88.2 ∓4.8 min) and total postoperative ICU time of 23.0-647.4 h (mean 97.9∓10.5 h). The postoperative complications included low heart output syndrome in 5 cases, bleeding in 4 cases, wound debridement in 4 cases, and hemodialysis due to acute renal failure in 1 case. The left ventricular end diastolic diameter reduced significantly after the surgery (52.6∓1.7 vs 43.2∓1.0, P=0.001). No significant changes were detected in the left ventricular ejection fraction (62.3∓2.5 vs 65.5∓1.3, P=0.257).

CONCLUSIONThorough preoperative examination, preoperative risk factor assessment, timely perioperative interventions, careful evaluation of patients' tolerance of surgery, and prevention of surgical complications are essential to decrease the perioperative mortality in elderly patients with CBAV.

Objective To validate of the Chinese system for cardiac operative risk evaluation (SinoSCORE) in Cantonese surgery patients. Methods Data from Guangdong Cardiovascular Institute in the period January 2004 through December 2008 were analyzed on 2462 Cantonese heart surgery patients. First, compared risk factors of this series and database of SinoSCORE, and then calculated the additive score of each patients and evaluate the discrimination and calibration of sinoSCORE in Cantonese patients. Results There were some differences between the risk factors of patients from two groups. The gender,smoking, diabetes, hyperlipemia, hypertension, chronic pulmonary diseases, stroke, cardiovascular surgery history, left main disease, atrial fibrillation/atrial flutter, pulmonary arterial hypertension, concomitant coronary surgery and concomitant valve surgery in Cantonese patients were different between two groups. However, The SinoSCORE was able to predict the in-hospital mortality of senior patients with good discrimination ( Hosmer-Lemeshow test, P = 0. 34 ) and calibration ( the area under the receiver operating characteristic curve, 0.84, P ＜ 0.01 ). Conclusion SinoSCORE was able to predict the in-hospital mortality of Cantonese heart surgery patients.

Objective To investigate the effects of interleukin-18 ( IL-18 ) on M cells of intestinal mucosa in acute pancreatitis (AP) in rats. Methods Seventy SD rats were divided into seven groups: AP 6 hour group, 12 hour group, 24 hour group, IL-18 6 hour group, 12 hour group, 24 hour group, and control group at random. The models of AP were established. Serum, pancreatic tissue, and ileal mucosa were harvested. Serum amylase, glutamate pyruvate transaminse, total bilirubin, endotoxin, IL-27, and TNF-α were detected. Pathologic changes of pancreatic tissue and ileal mucosa were observed. The protein with reverse transcription-polymease chain reaction (RT-PCR). Results The level of serum TNF-α increased obviously in IL-18 6 hour group, 12 hour group, and AP group. The level of serum IL-27 increased in IL-18 6 hour group and AP group and back to normal in IL-18 24 hour group. The in IL-18 group than AP group (P < 0. 05 ). Conclusions IL-18 may affect M cells function and play important roles in intestinal barrier in acute pancreatitis.

Objective To explore the effect of processized nutrition treatment strategy on the clinical efficacy of critically ill patients.Methods A prospective study was conducted, and 195 patients admitted to Department of Intensive Care Unit of Jiaxing Second Hospital from July 2016 to February 2017 were enrolled. From July to September 2016, 94 cases were assigned in the control group, and they were given the routine nutritional treatment program. From October to November 2016, the training of processized nutrition treatment strategy was carried out and improved according to plan-do-check-act (PDCA) cycle management plan, From December 2016 to February 2017, 101 cases were assigned in the observation group and treated by the doctor and nurse processized nutrition treatment strategy. The differences of early enteral nutrition (EEN) ratio, the time reaching standard of enteral nutrition (EN) in two group were compared, the incidence of complications related to EN, mechanical ventilation time, ICU hospitalization time, ICU expense and mortality were observed between the two groups.Results Compared with the control group, the ratio of EEN was significantly increasedin the observation group [90.1% (91/101) vs. 47.9% (45/94)], the time reaching standard of EN shortened (days: 5.18±1.43 vs. 6.47±1.95), the incidences of gastrointestinal tract related complications [0.77% (9/1173) vs. 1.67% (22/1319)] and ventilator associated pneumonia [VAP: 4.90‰(4/816) vs. 15.32‰(16/1044)] were obviously decreased, ICU hospitalization time (days:11.61±5.93 vs. 14.03±8.27), mechanical ventilation time (days: 8.08±6.16 vs. 11.11±7.87), the mortality [23.76% (24/101) vs. 31.91% (30/94)] were significantly reduced in the observation group (allP < 0.05), but the ICU hospitalization expenses had no significant difference in observation group and control group (millions: 7.26±7.23 vs. 7.07±4.60,P > 0.05).Conclusions The processized nutrition treatment strategy can improve the EEN implementation rate of critically ill patients, help to establish EN as early as possible, reduce the incidence of gastrointestinal and pulmonary infections and other complications.
